Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a punching and image exposure system for punching holes in a plate and exposing an image.
[0002]
[Prior art]
Conventionally, as an image exposure device that manufactures a printing plate by exposing an image to a plate made of a thin plate such as aluminum, the plate is wound around a rotating drum, and a light beam corresponding to image data is exposed while rotating the plate together with the rotating drum. There is known a technique in which scanning exposure is performed by irradiating a plate from a head (see, for example, Patent Document 1).
[0003]
By the way, there is a method in which a plate (printing plate) on which an image has been exposed is wound around a rotary press and a punch hole serving as a reference when printing is formed on the plate before or after image exposure. A punch apparatus for punching such punch holes is prepared separately from the image exposure apparatus, and the image exposure apparatus has a configuration having only an exposure function. When using this configuration, it is necessary to perform image exposure on the plate with an image exposure device, and punch holes with a punch device at another location (the order of image exposure and punch hole drilling is arbitrary) .
[0004]
As described above, when using an apparatus having a configuration in which the punching apparatus and the image exposure apparatus are independent, the image exposure process and the punching process are performed at different locations, so that the exposure position of the plate and the punching position are likely to be displaced. . If there is a shift between the two positions, a shift occurs between the image exposure position and the printing position where the printing plate is used. Therefore, it is necessary to accurately match the exposure position of the plate with the punch position.
[0005]
In the above conventional apparatus, as a plate positioning method, a notch for positioning is formed at the tip of the plate by a puncher, and this notch is fitted into a positioning pin protruding from the rotating drum or a positioning pin provided in the punching device. Thus, a method of positioning is taken.
[0006]
As another plate positioning method, a mark called a registration mark is applied to a part other than the image area of the plate by exposure, and the plate is positioned by measuring the mark and moving the plate according to the mark. Techniques for performing are also known.

[0064]
Next, plate positioning in the punch device 16 will be described.
[0065]
First, size information such as the length, width, and thickness of the plate 12 is input to the control unit 163 by the size input unit 160. In the case of the embodiment shown in FIGS. 9 and 10, information from the size input unit 150 or the size / punch type input unit 156 of the image exposure apparatus 10 is input to the control unit 163. No input operation is required. Based on the signal from the control means 163, the second reference pin 36B moves by the amount of movement calculated from the width size information of the plate 12.
[0066]
Next, the plate 12 is manually placed on the guide plate 5, and the front end is brought into contact with the second positioning pin 52B and the side is brought into contact with the second reference pin 36B. Since the first positioning pin 52A and the first reference pin 36A in the image exposure apparatus 10 and the second positioning pin 52B and the second reference pin 36B in the punching device 16 have the same relative position, the plate 12 In the punch device 16, three-point positioning is performed at the same position as in the image exposure device 10. Next, punching is performed by the puncher 46A or 46B selected by the punch type input means 161 or the size and punch type input means 156.
